LEZUG DAVID M. HOLBROOK, OF PORTLAND, OREGON.

SHUTTER ATTACHMENT FOR WICK-FED BURNERS.

l Application filed December 13, 1923.

To all 'whom t may concern:

Be it hereby known that I, DAVID M. HoLBRooK, a citizen of the United States, residing in the city of Portland, county of Multnomah, and State of Oregon, have invented a new and usefull Improvement in a `Shutter Attachment for Wick-Fed Burners, of which the following is the specifica tion. y

My invention is a device of such construction that the shutter attachment can f be attached to a wick fed burner and by the raising or lowering the shutter cover blade the iiame of the lamp or stove can be conl5 trolled. y

The object of my'invention is to construct a device that can be attached to a wick fed burner so that the shutter wick cover blade can be lowered or raised and thereby control and regulate the iiame.

I obtain the objects in the manner illustrated in the accompanying drawings and set forth in the speciiications following referring to the drawings.

Figure l is a sectional elevation of the shutter attachment and the burner; Figure 2 is a top plan with parts broken away of the shutter attachment and the burner.

p Similar letters and numerals of referencerefer to the same or similar parts throughout the several views. i

This attachmentis constructed by means of a bent arm 3 having a shutter wick cover blade 3a at the upper end thereof and at the lower end thereof a counterweight` 6 attached to counterweight arm 3b said bent arm 3 is attached to a spindle t; the bent bar 8 near the ends thereof is bent at right angles and at each end thereof is the bearings 7 through which spindle 4 is fitted; the spindle arm is indicated by 5; l is the burner and 2 is the wick.

serial No. 680,484.

Vith my device constructed by the foregoing parts and shown in my drawing, the shutter attachment can be attached to a burner by means of the bent bar 8, and when so attached the shutter wick cover blade 3 is so constructed that it will cover the wickwhen lowered leaving only a small portion of the wick uncovered just enou h 5o to keep small flame burning as shown y the drawings.

It will be observed that the shutter bent arm 3 can be lowered any desired distance or on top of wick 2 and that the control of 55 the fla-me is correspondingly lowered or raised in accordance with the contact with the shutter arm or when in contact when the wick is shut off entirely except that part of the wick left free as shown by the drawings.

This device can be attached to any wick burner such as is used on common kerosene lamps or stoves or any wick burners. I am aware that such burners have been used for a long time and I do not claim on account of the burners.

I claim:

In a shutter attachment for wick 'fed burner, a bent arm, a shutter wick cover blade at upper end of said bent arm, a counterweight arm at the lower end of said bent arm, a counterweight attached to said counterweight arm, a bent up bar with a bearing at each end thereof, a spindle extending through said bearings and attached to said bent arm substantially as described.

In witness `whereoLYI have hereunto set my hand'in the presence of two subscribing anything witnesses.
